Processing and preservation of agricultural produce using renewable energy sources and technologies
The focus is in processing and preservation of agricultural produce using renewable energy sources and technologies to improve livelihoods and empower communities, especially those in rural areas.
Use of alternative building materials in the construction industry
The focus is on the use of alternative building materials in the construction industry (e.g., buildings and roads) and the application of modelling and simulation in engineering.
Agricultural mechanization
The research focus is in the area of agricultural mechanization for improved livelihoods for smallholder farmers, and in environmental engineering (e.g., waste management, air quality and air and noise pollution control).
Application of modelling and simulation in engineering
The focus is in the application of computer modelling and simulation in: processing and preservation of agricultural produce; use of alternative building materials in the construction industry; agricultural mechanization. In addition, The interest is in the promotion of research that is adaptable and impacts positively to society in terms of economic, social and environmental benefits.
